Be 1t known that I, HIDALGO MoYA, cititaming frame.

I I s zen of the United States of America res f 5 drawings which mg at North Evingttm 1n Leiceste 3 cco din to hi England, have invented certain new as a a side View of so useful Improvements in lypefiVriters, or necessary to a which the following is a specification.

This invention relates to typewriters of the kind in which a type-bar base is detach-- able carrying with it type-bars, typolevers, key-levers and associated mechanism, so that another base may be substituted therefor to print characters of a different type, as for example in a different language. i

Theinvention is particularly applicable to typewriters of the kind in which the typebar base is support-ed on a pair of rocking bars or on a movable yoke and is movable to print the particular font required this movement being eiiected by a shift key mechanism which is also provided with a locking mechanism to hold the type-bar base in any one of the desired positions.

This invention consists in the combination, in a typewriter having a removable type-bar base, of two retaining members movably mounted on the frame to engage the type-bar base with, and disengage it from, the frame and means for locking one of these members relatively to the frame prior to releasing the base whereupon the second member may be moved relatively to the first member to release the type-bar base.

According to a further feature of this in vent-ion there is provided in combination with. the ordinary shift key and locking mechanism for moving and locking one of the retaining members, means for locking the other retaining member to the frame so then moving and locking the first member, the type-bar base is disengaged, so that it can be lifted out of place.

According to yet another feature of the invention, there is provided in combination withthe two retaining members a distance strut which holds them apart during normal operation, but which can be displaced to allow them to approach one another for releasing the type-bar base. In the preferred construction the distance strilt also acts as the locking means for one of the retaining members to whichitis pivoted, so that in one position it acts as a strut and when dis- ".ition, shon positioii.

he parts in the type-bar base released lifted out. v

Like letters indicate like out the drawings.

In order to simplify the specification the mechanism on one side only of the type writer will now be described. but it will be understood that some parts of such mechanism are duplicated dn the other side of the machine.

parts through assoc mecaan 1 cuntec o has on is termed the type-bar base 4..-. The ordinary rocking har B by the movement by which the various fonts brought into alinemenifor printing, is piv' oted at C to the frame of the machine. It will be understood that this and the corre sponding bar on the other side of the machine may be replacec by a single yoke as is used in some forms of typewriter. A second pair of detent bars D (which may also be replaced by a yoke) are fixed to the frame of the machine.

The rocking bar B is provided with a usual form of shift key F and locking mechanism G which are operatively connected by a link the bar B so that depression of the shift-key normally causes the bar B to rock forward and carry with it the type-bar base to print a different font. A notch or recess F; is provided at the upper end of the bar B and a similar notch L at the upper pivoted at D a distance strut I) having a.

bar B, so that when it is in the position shown in Fig. 1, it prevents the barsB and D approaching one another, thus reinforcing the action of the spring. The pin IV is so positioned that when the normal font is in use 2'. 6. when the type-bar base is in its farthestbackward position. the strut D on being raised will cause the hook D? to engage the pnrlV and lock the detent bar-D in that position, at the .same time releasing "the rocking bar B with respect to th e detent bar D. The depression of the shift keyF can now cause the rocking bar B to move forward against the action of the spring N toward the detentbar D thereby diminishing the distance between the notches K'. and

L at their respective upperends so that it I is possible to remove the type-bar base therefrom. The distance strut D is so shaped at the end D -wlierewith it; engages the rocking bar B that when the latter has been ad'- vancefl? toward .the detent bar D, the member D is engaged by a part of or a projectionon the rocking bar B and is thus prevented from falling and releaslng the detent bar A finger piece D? isprovided on the member D by which the latter may be raised or low ered as required;-

Assuming thatthere is a type-bar base. in position. and that it is required to replace it, the operation is as follows :-The distance strut D at each side of the machine is raised engaging its corresponding pin IV thereby locking the detent bars in position; the typebar base is then held steady and the shift key lever depressed and locked whereby the rocking bars B are drawnforward and held in that position; a slight forward and up-- ward movement then releases the type-bar base so that it can 'be removed. The new type-bar base is now.placed in position so that the pins M engage the notches-L on the detent bars D. The shiftkev mechanism is released and the rocking bars. B tilt.

to secure by Letters Patent is 1. In atypewriter having a removable type-bar base the combination of, two re-.

taining members movably mounted on the frame to engage the type-bar base with. and disengage it from, the frame, and means for locking one of said members relatively to the frame prior to releasing the base whereupon the second member may be'moved relatively to the first member to release the type-bar base, substantially as described.

2 In. a typewriter having a removable type-bar .base the combination of, two retaining members movably mounted on ,the frame to engage the typebar base with, and disengage it from, the frame, means for locking. one of said members relatively to the frame prior to disengaging the base and means for locking the second member after it .has been -moved relatively to the first. member when locke'd to release thetypebar base, substantially as described.

I 3. In la typewriter having a removable type-bar base the combination of, two retaining members movably mounted on the frame to engage the type-bar base'with, .md

disengage it from, the frame, means for locking one of said members relativel 'to the frame prior to releasing the base, and shift-key locking mechanism (Gr) cooperating with the second member fonlocki-ng it. after it has beenmoved relatively to thefirst member to release-the type-bar base, sub stantiallyas'set forth. i
